    Just updated LSSS to the latest DOTS moving from 2020.1.9f1 to 2020.3.30f1.

    My custom physics code seems to have tripped up Burst again. This time, it only triggers when safety checks are enabled.

    Link to the project (the last two commits are the migration process, so HEAD and HEAD~2 are the versions to compare): https://github.com/Dreaming381/lsss-wip/tree/ae879dabdc0b0fb42934db3a211b91aa8036b62f

    Full error:

    Thanks for digging! I got to pulling your project and got some editor errors with conflicts on cecil I think, then had to context switch. I'll try repro again soon though (maybe I need to remove the custom cecil in your manifest, not sure!)

    Thanks for attempting to look at it. Any custom cecil is leftover from a long time ago and should be removed. I thought I removed it, but now I am wondering if Unity still has a hidden reference somewhere.
